HARRY G. MILLER, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO MILLER SAW-TRIMMER COMPANY OF MICHIGAN, OF ALMA, MICHIGAN, A CORPORATION OF MICHIGAN.

Specification of Letters Patent.

Application filed July 13, 1908. Serial No.'443,402.

Toall whom it may concern Be it known that I, HARRY G. MILLER, a

- citizen of the United States, residing at Mil- \vaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Sawing and Trimming Machines with Router and Jig-Saw Attachment, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to means for operating upon half-tones, stereotype and electrotype cuts and like articles.

One of the objects of-my invention is to provide a machine for preparing half-tones, stereotype and electrotypecuts and like articles for insertion in theprintin form. My machine is designed for performing the necessary sequence-of operations upon the above articles to prepare the same in such a manner that the articles Will properly fit in the form and present the proper'printing surface for making the desired impressions.

Another object of my invention is to provide a machine in which a single positioning device will cooperate with the various parts operating upon the above-mentioned articles, whereby the operations -.upon the article will have a definite relation to one another and there will be no variance in measurement or otherwise which will affect the positioning of the out in the form or the impression made thereby.

For the purpose of disclosing my invention, I have illustrated in the accompanyin drawings one of the practical forms whic my invention may take.

In said drawingsFigure 1 is a front elevation of my machine; Fig. 2. is a side elevation of the same; Fig.3 is a top plan view of my invention; Fig. 4 is a plan view of my machine, with the jig-saw and routercarrying arm swung to one side; Fig. '5 is a front elevation of my machine, with the jig-saw and router arm swung to one side;

Fig. 6 is a partial sectional view of my jigsaw and router-carrying arm; Fig. 7 is an 'end view, partially in section, .0 the jigsaw and router-carrying arm; Fig. 8 is a detail sectional view on the line 8-8 of Fig. 5, and Fig. 9 is a sectional view on the line 99 of Fig. 1.

- In the embodiment of my invention illustrated I provide a base or pedestal 9, upon wh1c h is mounted a sliding bracket 10, supporting a relatively stationary table 11, which in turn has slidably mounted thereon Patented June 25, 1912.

an'auxiliary table 12. A second bracket 13,

which-is preferably integrally formed with the pedestal 9 and extends transversely upon the opposite side of the pedestal, has pivotally mounted thereon a hollow standard 14 having a transversely extending hollow arm 15. The pedestal 9 is provided with atongue 16, which engages a groove of counterpart shape forme in the bracket 10. In a lug 17, formed on the bracket 10, is journaled a' shaft 18 having a threaded portion 19, which engages a threaded opening formed in a lug 20, integral with the pedestal 9. The upper extremitg of the sha t 18 is provided with a bevele gear 21, which meshes with a gear 22 fastened on a horizontal shaft 23 journaled at one extremity in the bracket 10 and at the other extremity in a relatively stationary bracket 24. The outer extremity of the shaft 23 is provided with a crank 25, whereby the shafts 23 and 18 may be manipulated for the purpose of raising and lowering the table upon the pedestal. To the outer extremity of the shaft 23 is also secured a gage-wheel 26, which is graduated I or subdivided into points or portions of a pica,the unit of measurement in typographical matters. These graduations indicated upon the gage-wheel are adapted to coincide with a pointer 27 relatively stationarily mounted upon. the table 11. In adjusting the position of the table the gage-wheel which turns with the shaft 23 will'indicate the exact elevation imparted to the table in points or sub-divisions of the pica. In practice, the gears 21 and 22 have such relation to each other that for every rotation of the shaft 23 the screw-shaft 18 will begiven two revolutions, and the pitch ofthe threads 19 on this shaft are so regulated with reference to the sub-divisions or points indicated'on the gage-wheel that the user of the machine is able to determine by the movement of the gage-wheel the exact vertical movement imparted to the table through the instrumentality of the mechanism already described.

A saw 28 cooperates with the sliding table 12 and is mounted on a shaft 29 journaled in bearings 30 extending upwardly from and formed integrally with the pedestal 9. Thisthe operator.

saw is preferably mountedon the front face of a trimmer-head 31, which is removably mounted u on the end of the shaft 29 and is provide with trimmers 32 which project through suitable openings in the face of the.

contact with the saw teeth and revent-ing chips and dust from flying in t e face of The positioning gage above described cooperates with the sawing and trimming device to properly shape the cut. The gage ositions the Work in respect to the trimming device and determines the proper measurement thereof. The sawing and trimming device trims the vertical edges of the cut so that the same will not only be of the proper size but will have the proper shape to lock up rigidly in a predetermined manner'in the printmg form.

Upon the top of the sliding table 12, at the front end thereof, is mounted a gage for properly positioning the stock or material to be operated upon by the devices of my invention. This gage consists of a gageplate 37 and a straight edge 38. The. gageplate is provided with a-toothed rack 39, in which are adapted to fit the threads of a worm 40 mounted upon the straight edge 38. A suitable lockingdevice 41 is also provided. on the straight edge 38 for locking the worm 40 against movement when it hasvbeen set to any desired position. The top of the gage-bar or gage-plate 37 is marked with A zone at graduatio-ns to indicate picas. one extremity of the worm is graduated to indicate points, the entire circumference of the zone being divided intotwelve points,

which is equal to one pica, and the teeth of the gage-bar are so constructed with reference to the worm that a complete turn of' the worm will move the arm 38 forward a distance of twelve points indicated by the graduations marked on the worm. The gage-bar 37 is secured in position upon the sliding table by a suitable pin 42, which, at its lower end, is provided with a washer 43 ada ted to fit in a recess formed beneath the slidmg table 12, and at its upper end is provided with a threaded nut 44. The pin is adapted to extend through an arc-shaped slot 45, and when the nut 44 is screwed tight the gage-bar 37 will be securely clamped in position. A second pin 46 is adapted to enter suitable openings 47 in the table 12 to hold the outer end of the bar rigid, By this arrangement the gage-bar37.

may be swung to any angular position relative to the saw in order to get the various de rees of angular cuts desired.

or holding the work in position against movement, I provide a suitable work-holding device, which consists of a casing 48 removably secured to the table 12 by means of a locking nut and a slidable plunger 4!), which is adapted to engage one side of the work and force the same against the gagebar 37. This plunger 49 is preferably moved forward by a handle or rod 50, which also operates alocking mechanism (not shown) for'holding the plunger in any position to which it may be moved.

.After the out has been shaped by the sawing and trimming device in connection with the positioning means the next operation is the preparation of the horizontal surof the out, including the printing-surface.

This means consists of rotary tools andof reciprocating tools arranged to be secured in tool-holders carried by a pivoted overhanging arm 15.

It is sometimes desired to raise the table. To this end the opening in the top of the table 11, which accommodates the shaft carrying the saw and trimmer, is closed by a movable table part 51, which is hinged, as at 52, at one end, the other end being free and adapted to rest upon the journals of thesaw shaft. As the table is raised, which operation brings it above the saw proper, this hinged portion will drop and close the opening which accommodates the saw shaft, giving a greater working area for supporting the work thereon.

The reciprocating tool-holder comprises a vertically movable plunger 58, which is adapted to reciprocate in a suitable journal 54 formed at the end of the hollow trans- Versely extending arm 15. This plunger is rovided with a-suitable slot 55, in which 15 jo-urnaleda roller 56 adapted to fit within aslot 57 formed in the end of the arm 58 mounted within the hollow arm 15 and pivotally connected thereto at 59. The rear end of this arm is connected with a rod 60, which extends downwardly in the hollow vertical standard 14 and is provided at its lower end with an adjustable nut 61, against which rests a coil spring 62, the opposite end of the spring being adapted to rest against the boss or projection 63 in the hollow arm 14, whereby a tension is exerted upon the rear end of the arm 58, which serves to maintain the plunger 53 in its upward or normal position. The forward end of the arm 58 may be moved downwardly at will by a bell crank lever connection which comprises an arm 64, having a roller 65 thereon'adapted to bear upon the upper side of the arm. 58. This arm 64 is pivoted at 66 to the transversely extending arm 15 and is connected to the opposite bell crank arm 67, which is mounted exteriorly of the hollow arm 15 and may be manually operated or connected with a foot operating mechanism as may be desired. A suitable coil spring 68 is inter ose'd between one end of the arm 67 and a oss formed on the arm 15, to aid in main.- taining this arm in its normal position.

The lower end of the plunger 53 is provided with a slot 69, in which is adapted to fit one end of a jig-saw 70, A transverse pin 71 extending through the jigsaw rests in suitable channels 72 formed in the side walls of the slot 69 to maintain the ig-saw connected to the plunger, The lower end of the jig-saw is connected by a suitable connecting member 73, similarin construction to the connecting member for the plunger 53, with a reciprocating member 74 adapted to reciprocate in a suitable guide 75 mounted beneath the table 11. The lower end of this reciprocating member is connected with an eccentric pin 6 mounted upon the wheel 77 carried on a suitable shaft 78, journaled in a transversely extending arm 79, which arm, in practice, forms a part of the casting constituting the vertical arm 14 and the transverse arm 15.

The shaft 78 is driven from a gear wheel 80, the shaft 81 of which is provided with a square-jawed clutch 82 and is transversely movable so that the two members of the clutch may be moved into and out of engagement as desired. The opposite end of the shaft 81 is provided with a second squarejawed clutch 83, which is adapted to mesh with a second shaft 84, the object of which will more fully appear hereinafter, The shaft 81 is moved transversely by means of a sliding pin 85 mounted in a hollow boss 86 on the arm 79 and having a suitable channel 87 therein, in which channel the gear 80 is adapted tooperate. By sliding the pm transversely one way or the other, the gear 80, andwith it a shaft 81, may be moved backward and forward to. cause the clutches 82 or 83 to engage. p

The rotary tool-holder comprises a spine dle 88, which is of the usual construction and need not here be described in detail, and in which may be secured any instrument, such as the router 88; This spindle is mounted upon the end of a shaft 89, having secured at the upper end thereof a driving pulley 90 and mounted in ajournal 91,

which is vertically movable in the end of the arm 15. The upper end of the journal is provided with an annular flange 92, which has a recess 93 therein, large'enough tore ceive the reci rocating plunger 53. When, however, the stage is turned so that this recess is out of alinement with the lunger,

the flange is adapted to fit in a channel 9 1 formed in the upper end of the plunger, whereby the movable journal 91 and the plunger 53 are connected together, so that the router may be raised or lowered bythe (1, 7

bevel gear 99, adapted to mesh with a bevel gear 100 carried on theshaftBet. The castmg forming the arms 14,- 15 and 79 is pro: vided with a suitable pin 101, which fits in a socket formed in the arm 13, ,wherebythe head carrying the jig-saw and router may beswung into or out of sition.

The arm 79 is locked in operating position by means of a bolt 102, which, when the arm is swung into normal position, fits within a slot 103 formed on the arm 13, and which screw-threads into the bottom of the arm 79, so that by tightening the bolt 102 it will engage the flange formed on the arm 13 and rigidly hold the router and jig-saw attach-.

a position beneath the flange 92. By thisarrangement I am enabled to provide an adjustable stop to control the depth of the cut made by the drill or router 86,by controlling the distance the same may be lowered by the arm 67. The difference inheight of each of the points is just one point, so that the depth of the cut made by the drill may be measured in conformity to printers measure.- In order to obtain a greater range of measurement, I provide a removable cap 106, which is one-half point in thickness and which maybe placed on any one of the points so that a variation of half a point maybe obtained.

When the transverse arm is swung into position thetable 11- if need be may be raised sufli'cientl to bring it to a position where the arm 79 can be swung under the same. When the arm 15 is swung into position, the gear 80 will mesh with a driving pinion 107 mounted on the end of the shaft 29.

The operation of the machine may be more clearly understood if first I point out the nature of the cuts asthey come from the maker of the same. When the cuts are received in the printing oflice from the maker the blocks on which'they are mounted, or other bases, are not square or the sides do not form true right angles so that the samewill lock up properly in the form. Neither are: the bus: or blocks cut accumade, say, for insertion in different newspapers, it is necessary that some of the printing matter must be changed either by taking out some of the printing matter or by substituting for some of the printing matter other printing matter. Vith this understanding the operation of the machine in the preparation of a cut may be more fully appreciated. The first operation of preparing the cut is to prepare the vertical sides so that the angles of the cut will all be true and the cutwill have the proper measurement to fit in the form. In this operation one of the vertical edges is given a slight trim by the rotary sawing and trimming device to true that edge. This edge is then used as a basis for the remaining operations. After this edge has been trimmed the movable member of the gage is set to give the proper measurement to the cut in one direction, say, the -width. The trimmed edge is then placed against the movable member and the opposite edge ora vertical side is trimmed. This gives two sides of the cut with proper dimensions and both sides are perfectly straight. The cut is then turned to one of the remaining unt-rimmed sides and this side is likewise given a slight trim to true it up with respect to the other two trimmed sides. The movable member of the gage is again set to give the cut the proper dimensions, say, lengthwise, and the remaining edge or vertical side of the cut is trimmed. The vertical edges of thecut are now trimmed insuch a manner that all the edges are perfectly true, form- .ing the correct angles and having the correct measurement to cause the cut to fit in the form in such a manner that it will properly lock up and in such a manner that no other adjustment is necessary.

After the vertical edges of the out have been prepared the horizontal surfaces may be prepared. The cut is not always of the proper vertical height to fit in the form, or, as it is technically expressed, is not type high. In order that the horizontal surfaces of the cut may be used, the cut is turned over on its face and positioned by the same positioning device which was used with respect to the sawing and timming device beneath the rotary tool-holder. The proper tool is inserted and the rotary toolholder is lowered until it is in the exact position co plane the bottom surface of the cut type high. Bythe operation of the sliding-table backward and forward and by advancing the cut by means of the movable member of the gagethe bottom horizontal surface of the cut is trimmed until the out is exactly type high. After this operation the cut is turned over, and, if there is ter.

subject-matter in the printing surface which reciprocating tool, which may be in the form of a reciprocating saw, is Inserted in the reciprocating tool-holder and the subject-matter tofbe taken out is cut out b removing the entire portion of the blocit carrying this subject-matter. Likewise, if new matter is to be inserted in place of that which has been taken out, the proper tool may be inserted in the rotary tool holder to drill out the old subject-mat-ter'and form a hole or opening in the block for the insertion of say a type, or if it requires more space than merely one type,'the reciprocating saw or other tool may be used for cutting out from the block sufiicient material to permit the insertion of the new subject-materations, however, the same positioning device is used to position andmeasure the work. By this-arrangement ther is no variance to the units of measurement and the cut will always properly fit in the form and lock up in such a manner as to give the best results.
